Tips to Keep Your Trees Alive During the Drought

1. Deep water mature trees slowly at least once or twice a month in the summer. Water within and slightly beyond the dripline, keeping the trunk dry. (Trees in sandier soil need to be watered more often than those in heavier soils.)

2. Keep the roots of newly planted trees moist their first season. Apply water regularly (2-3 times a week). 

3. Water early in the morning when soil water evaporation is lowest.

4.  Remember to water your trees that may have been relying on lawn sprinklers if you take out your grass.

5. Contact the UCCE Master Gardener Helpline for more tips: mgsanbern@ucanr.edu
